A Correct answer
Explanation

The Aravalli Range is the oldest mountain system in India and one of the oldest in the world, dating back to the Precambrian era (approximately 3.5 billion years ago). The Himalayas are relatively young (about 50 million years old), formed by the collision of the Indian and Eurasian plates. The Nilgiri and Satpura ranges are also much younger than the Aravallis.
